' CARDOOR.

house cars, such as automobile, refrigerator,

furniture and stock cars, being more especially adapted to box cars.

The object of our invention is to provide a door for cars of the class.enumerated, which will be fiush with the car-sides when in closedposition; at the same time provid ing a door which will be air-tight andwaterproofand so constructed, that when locked and sealed, will bepositively burglar-proof because of the impossibility to open the doorwithout first breaking the seal.

A further object'of our invention is to provide a door, especiallyintended tobe made of steel or metallic plates, which will be simple indesign, strong in construction and yet inexpensive to manufacture;:theinvention possessing a number of advantages, aside from thoseenumerated, inherent in the construction and which will be readilyapparent, from the following detailed dewherein scription of theaccompanyingdrawings,

In the exemplification of our invention, we have illustrated thedoorcomposed of a number'of metallic sections 15, shown arrangedlongitudinally of the door, namely in a horizontal direction; therespective sections having their edges orsicles flanged and preferablypresented outwardly so as toprovide the reinforcing orstiifening ribs16; the flanges of adjacent sections being secured together in anysuitable manner as, for" example,'by rivets and the like. I i i rectionof the arrows, illustrating a modified The top of the 0100 -1 showniprovided with suitable roller-containing hangers 17, the rollerswhereofare adapted to ride along or -moveon. the doorscarrying "rail.vThe door-carrying. rail is made in sections, one portionor sectionftowit section 18,-being pivotally mounted, while the other portion i orsection 19 is stationarily secured along the upper side of the car inany wellknown manner, V

The section 18 is pivotally mounted at 20, by means of any suitablehinge or bracket, to the side of the car adjacent toand above thedoor-opening, as more clearly shown in Fig. 1. This construction permitsthe free or opposite end of the rail 18 to be moved into and out ofalinement with stationary rail 19; the pivotal section of the rail, inFig. 4:, being shown moved out of alinement, while in Fig. 5 it is shownswung into alinement with rail 19. l j

The bottom of the door is shown provided with suitable guidesor'brackets 21 which engage with the door-rail beneath the bottom of thedoor. This rail, like the doorrail above the door, is composed of apivoted section 22 suitablyhinged or pivoted at 23 to the side of thecar, and a stationary section 24 secured to the car-side; the pivotalsection 22 being pivoted so as to permit the free end'to be swung intoand out of alinement with the stationarily secured section 24, see Figs.1 and 6. a

The mechanism for operating the railsection 18, and therefore also thedoor, comprises a suitable lever 25, which we will term the sealinglever, fixedly secured to the vertically disposed operating rod 26,which is held by means of suitable brackets 27, 27,

more clearly shown in Fig. 6, secured to the side of the car so as toreceive the upper and lower ends of rod or'shaft 26, and at the sametime permit the latter to rot-ate;

it being understood, of course,that rod 26 is held against verticalmovement or displacement.

The door-rails, both at'top and bottom, are preferably made of Z-bars,as more clearly shown in the detail cross-sectional portion shown to theright in Fig. 4 at 19*, although these rails may beeither made ofchannel iron or angle iron, arranged so as to provide a horizontallydisposed flat portion or leg, as, for example, shown in Figs. 11 and 6,respectively.

As the mechanism, whereby the pivoted sections of the door-rails areoperatively adapted to extend connected with rod or shaft 26, isidentical both at the top and bottom of the door, a description of themechanism, for example at the lower part of the door, as illustrated inFig. 6, will suflice.

The mechanism just referred to comprises anarm 28 fixedly secured to therod 26 so as to be rotated therewith, the opposite end being pivotallysecured to the link 29 which, in turn, is pivotally secured to arm 80.The arm 30 is provided witha pin 31 which is into the slot 32 of thepivoted rail section. 5

' It will be noted that the operating mechanism at the upper end of rod26 is located above the sectional-rail 18, while the mechanism at thelower end of rod 26 is located beneath the sectional-rail 22, so thatthe pin 31, provided on arm 30, is presented upwardly at the lowerpart'of the door and presented downwardly in the mechanism above thedoor. The pin 31 is preferably carried by arm 30 at the end which ispivotally connected to link 29; the opposite end of arm 30 beingpivotally connected at 33 to the outer end of the bracket 27.

It is evident from the construction shown and described that the arm 30will be placed.

under compression, that is, at right angles to the plane of the doorwhen the door is closed, so that any pressure against the door from theinside will be on a dead center with the arm 30 and hence will not havea tendency to operate the mechanism, and therefore will not break theseal of sealing lever 25; arm30 constituting a self-locking mechanismwhen the door is in closed position.

In Fig. 6 the position of the operating mechanism is shown in full linesin the position it occupies when the sectional-rail has been moved outof alinen'ient with the doorrail 21 and the door moved to closedposition; the dotted lines indicating the posi tion of the various partswhen the door is moved outwardly, preparatory to being rolled intocompleteopen position; namely to the position where the free end ofsectionalrail 22 is moved into alinement with the stationarysectional-rail 24. When lever 25 is moved to the position shown indotted lines in Fig. 6, it will rotate shaft or rod 26, thereby swingingthe pivotal point 21 of arm 28 to the point shown in dotted lines at 31,thereby carrying pin 31 to the point indicated at 31. The pin 31,extending into slot 32 of rail 22, in its movement through the arc of acircle as indicated in Fig, 6, swings the free end of rail 22 outwardand into register with rail 21.

It will be understood, of course, that the rotation of rod or shaft 26will induce the mechanism at theupper end of the rod to move in asimilar manner, and therefore cause the sectional-rail 18, above thedoor, to also move outwardly and into register with the rail 19. Withthe sectional-rails 18 and 22, moved to the position indicated in dottedlines in Fig. 6, the door may be rolled along the pivoted sections 18and and onto the stationary sections 19 and 241.

18 and 22, when the lever 25 may be swung;

back to the position indicated in Fig. 1 and i in full lines in Fig. 6,when the lever will pass over the staple 35, where'it may be sealed inplace. The movement of lever 25, as just described, rotates rod 26 andwith it the levers, and links previously described, so that the latterassume the position shown in full lines in Fig. 6, which will throwthepivoted' rail-sections out of alinement with the stationarysectionsand force the doorinto the door-opening in the car-side and thereforeflush with the car-sides.

The pivoted rails. are prevented from swinging outwardly too far bymeans of a suitable bracket 36 secured to the car-side beneath the freeend of bottom-rail 22; the

bracket 36 being preferably provided with atransversely disposed slotshown at 37 in F ig. 6, which receives a pin 38 secured to thebottom-rail 22. The top rail may be. provided with similar mechanism,although. the limitation of movement of bottom-rail 22' ,will, ofcourse, by reason of the door-connections to the rails, transmit similarlimitation in movement to the upper door railsection 18. Thisconstruction and arrangement makes the door absolutely'fool-proof, andat the same timepermits it to be easily operated. 9

In order to provide a weather-proof construction, we prefer toprovideweather-strip 39, see Fig. 5, and the reverse curved flange: 40 atopposite sides of the door, and a weather-strip 41 which is secured tothe car-,

side above the door, as shown in Figs. 1 and 3; the bottom of thedoorbeing preferably made to overlap the side-sillsof the car, as

can more clearly be seen in Fig. 3, in such a'manner as to preventmoisture from entering the car from that direction.

The top of the door is kept on the pivoted proper operative relationwith the. rails.

The bottom of the .door is prevented from jumping 'ofi of thebottom-rail by means of the brackets 21 which are preferably providedwith a depending portion or lug adaptedto extend to the rear of-theupwardly presented, portions of the bottom;

rails, as clearly shown in Fig. 3; the relation of the parts just.described beingpb tained by slidingthe door. into POSltlOIl,

namely onto the door-railsbefore the doorstop 43, see Fig. 1, is securedto the side of the car.

We have illustrated main doori pro vided witha small doorl44 intheupper' p artthereof, and a door 45 inlthe lower, part thereofptheupper smalldoor 44 being used" for the purpose of filling the car,after the main door has been'closed, with such com-v modities as loosegrain, coke, charcoal, and

the like; while the lower door 45 is provided for the purpose ofenabling the car to be other suitable manner.

emptied, or partially so, of similar commodities before the main door.is movedto open' position. V

The two. small doors 44 and 45 are shown suitably hinged to the maindoor, so as to swingupwardly,.andare, locked in closed position by meansof rod 46 to whichwis pivotally secured a sealing hasp 47, pivotallysecured at 48 to the main door- Mounted onthe lower door 45 is a smalllatch rod or member 49 provided with a spring 50 which maintains ayielding operative relation -be-. tween member 49 and rod46';.,latch-member 49' being adapted tohave locking engage ment with thebottom frame-portion about door 45; the frame-portion being either pro:vided by flanging the portion of the main door, adjacenttheropeningrwhich receives door 45, as shownin Figs. 3 and 9, or in anyByswinging the sealing hasp 47 about its pivotal point 48 so as tov movethe free end of the hasp downward, rod 46 will be pushed upwardly andstill remain in looking engagement with door: 44. This upward movementof rod 46, however, will permit latchmember 49 to move upwardlythroughthe action of spring 50 and therefore out of look ing' engagementwith the bottom framemember or door. 45, allowing door 45' to be opened.Movement of the free end of hasp 4 upwardly will depress rod 46 out oflocking engagement with door 44, while door 45 may still remain locked.

It is evident from the construction just de-- scribed that both doors 44and 45 may be independently opened by the movement of hasp 47 in properdirection, as previously described. As the latch-member 49 is carriedentirely by door 45 and is separate from the rod46, it is evident thatdoor '45 may be readily opened because the rod 46 will have cleared thedoor-frame when the latch-member 49 has been raised out of lockingposition.

It will be ardent m a anemia,

just described that one seal need be employed for securing the hasp 47onto the staple'5l. secured to the main door, as shown in Fig. l. Bysealinghasp-47 both smalldoors 44 and45- will be held locked, andtampering orrobbery of, the car, without breakingthe sealeither of hasp47 or of the main seal-V ing lever- 25, will be prevented:

In Fig. '11, we show the door-rail above the door madein the naturefof achannel, as canbe seen as l9 the rail section 19? being 52; The hang er17 4 being substantiahylike hangers 17 previ ouslydescribed, with the.hanger arranged r01 overlap the lower flange: ofthe rail-sectionsl8 and19?,andtheop- :shown securedin place by a suitable bracketeratingniechanism being similar to thatshown in the other figures, adetailedkle scription thereof neednot be entered into.

We have shown and described what we bearily mounted on the car-sidewhile the other section of each rail above and below the'door-opening ishingedly secured. at one end thereof so as to permit thefree end toswinglaterally and bring it into and out of alinement with thestationarily mounted section, means for slidingly mounting the door onboth top and bottom rails, and operating means connected with thepivotally mounted sectionv of both top and bottom rails, said meanscomprising a rotatable vertically disposed member, a pair of laterallyswinging arms pivotally mounted, one adjacent the top and the other atthe bottom of the door and adapted to be disposed perpendicular to theplane of the door when the latter is in closed position and therebyautomatically lock the door in said position, the free ends of said armshaving controlling relation with the free ends of the hingedrailsections, said members having controlling relation with said arms.
